@trusty-suire, The problem is not encoding. The problem is that codesys ands ' ' to the string. And the printer can't handle these character.

I think this will not work. I reworked and used an int as source instead.

In simulation mode there are no fieldbus updates possible - so this makes only sense with real devices.

Post by mehakfatima on Need Help Configuring Energy Analyzers via Modbus TCP & RTU (RS-485) in CODESYS 3.5 ^{CODESYS Forge talk (Post)}
Hello everyone, I am currently working on reading data from energy analyzers using Modbus TCP and RTU (RS-485). In my previous software, I used the following method to add slave devices (i have attached the image) and configure registers: Add the Modbus slave device. Configure the communication parameters (baud rate, parity, etc.). Define the registers and their addresses for data retrieval. Now, I am trying to achieve the same in CODESYS 3.5, but I am not sure how to configure the Modbus master, add slave devices, and set up the registers properly. If anyone has experience with Modbus TCP/RTU setup in CODESYS 3.5, I would really appreciate your guidance! A step-by-step explanation or any references/tutorials would be extremely helpful.

I would expect that this is more or less Bookworm related - the GPIO access is different now - and need to be adapted

Post by rickmotion on Opening and saving files with fileOpenSave dialog ^{CODESYS Forge talk (Post)}
I have a customer that types in machine programs in a text file for machines and lets the machine execute it. In the old situation they can open and edit these files in a winform application. Now I want to move this to codesys. What I need is a simple way to open, close, save, edit the machine file in codesys visualisation. I want to use the fileOpenSave dialog. But don't understand how it works. I have the file transfer example and some other examples. But it is hard to figure out how the part with the file dialog works so that you can select a folder or file. Does someone know how that works?

DO NOT use the same username and password in Codesys as your default Rpi OS admin user on the Pi.
